However, I remember the video well because I am in it. We made it for NHK Japanese national television in 1973, and it was distributed to countries all over the world. I am the person attacking Saito-sensei with a tanken in the beginning of the video, and appear throughout it.
And yes, I agree; let people watch and make up their own minds.
